This math skill involves using a map's scale to convert a real-world distance to the corresponding distance on a map when both are measured in the same unit. The process uses division based on the scale ratio.

Converting to a distance on a map, same unit, based on the map's scale
Test your understanding of converting to a map distance by practicing it! Work through the below exercises to use it in practice.
🎙️
How many decimeters on the map would represent 400 decimeters in reality if the map has a 1 to 100 scale?
🎙️
Map scales are a ratio. 1 to 100 is the same as the map measurement to 400
🎙️
So if we rearrange and simplify, 400 decimeters in reality is 400 over 100, or 4 decimeters on the map.
